UPDATE: Man who killed himself on I-24 in Marion County was wanted ex-police officer

The wanted man who authorities say killed himself alongside Interstate 24 in Marion County Tuesday was a former police officer who had been in trouble with the law before, Times Free Press archives show.

Charles Keith Murphree, 44, committed suicide between the towns of Jasper and Kimball on the westbound side of the interstate, bringing traffic to a halt Tuesday afternoon.

Murphree, a former police officer in Ider, Ala., was wanted in DeKalb County. Authorities identified the vehicle he was driving at the Western Sizzlin' restaurant at the Jasper exit. Authorities then followed Murphree west on Interstate 24 for a few miles before he took his own life, officials confirmed.

The Marion County Sheriff's Office received assistance from the Tennessee Highway Patrol before the Tennessee Bureau of Investigation took over the investigation.

In 2012, when Murphree worked as a police officer, he was charged with third-degree domestic assault.
